Abstract

Satellite-based measurements have been performed on EDM Calibration Base by Classic GPS, Network RTK and Static GPS methods and terrestrial measurements have been conducted with Total Stations in this study. FKP, VRS and MAC correction methods were used in the Network RTK method. The objective of this study was to make statistical comparisons of distances obtained by using all combinations between different measurement methods. Analysis of Variance (ANOVA) was utilized for this purpose. It was determined that there was a statistically significant difference between the measuring methods used in the one-way ANOVA test. The differences and standard deviations obtaind by the comparison of distances based on different measurement methods between benchmarks have been varied from mm to cm. The results obtained by the static GNSS surveying method are better than the standard deviations obtained by other methods of measurement and equipments when compared. The methods according to the distance measurement precision have been listed from the highest precision to low as Static GNSS, terrestrial surveying, classical RTK, FKP, VRS and MAC respectively. The distance measurement precision of Terrestrial measurement was found to be better than the classical RTK and NRTK measurement methods. The distance measurement precision of the classic RTK method was better than NRTK methods obtained by the different correction methods. In comparison, of NRTK correction methods in itself, the best results were obtained by FKP method.

Özet

Bu makalede, bir EDM Kalibrasyon Bazında Klasik RTK, Network ve Statik GPS yöntemleri ile Uydu bazlı ölçümler ve Total Stationlar ile yersel ölçümler gerçekleştirilmiştir. Network RTK yönteminde FKP, VRS ve MAC düzeltme yöntemleri kullanılmıştır. Bu çalışmada, farklı ölçme yöntemleri ile elde edilen pilyeler arasındaki tüm mesafelerin, istatiksel bir karşılaştırması yapılmıştır. Bu amaçla Varyans Analizi (ANOVA) kullanılmıştır. Tek yönlü ANOVA testinde kullanılan ölçme yöntemleri arasında istatiksel olarak anlamlı bir farkın olduğu belirlenmiştir. Farklı ölçme yöntemlerine göre pilyeler arası mesafe karşılaştırmaları ile bulunan farklar ve standart sapmalar mm'den cm'ye değişmektedir. Statik GNSS ölçme yönteminden elde edilen standart sapmalar diğer ölçme yöntem ve donanımlarına göre bulunan sonuçlara göre daha iyidir. Mesafe ölçme hassasiyetlerine göre yöntemler Statik GNSS, Yersel ölçmeler, Klasik RTK, FKP, VRS ve MAC şeklinde sıralanmıştır. Yersel yöntemlerin mesafe ölçme hassasiyeti, Klasik RTK ve NRTK ölçme yöntemlerine göre, Klasik RTK yönteminin mesafe ölçme hassasiyeti ise farklı düzeltme yöntemleri ile elde edilen NRTK yöntemlerine göre daha iyidir. NRTK düzeltme yöntemlerinde en iyi mesafe ölçme hassasiyetini FKP düzeltme yöntemi vermiştir.
